摘  要:
为探索超级稻龙稻5号的高产栽培技术模式,以龙稻5号为试验材料,进行了不同水平的栽培密度、氮肥和钾肥的田间小区试验,试验采用二次回归旋转组合设计。试验结果显示,制约龙稻5号产量的各因子顺序为:施氮量>插秧密度>施钾量。得出龙稻5号高于10500kg/hm2的高产栽培模式为栽培密度19.34~24.15穴/m2,施N量172.65~180.00kg/hm2,施K量34.05~67.2kg/hm2。

摘  要:
In order to exploring cultivation model of high yield of‘Longdao5’, plot trail of different level of density, nitrogen and potassium fertilizers by using orthology regression rotating method. The results were as follows: the sequence of factor which restraining yield of‘Longdao5’was nitrogen fertilizer >density of cultivation >potassium fertilizer, and cultivation model above 10500 kg/hm2 were as follow: cultivation density was 19.34 to 24.15 hills/hm2, fertilizing nitrogen was 172.65-180.00 kg/hm2 and fertilizing potassium was 34.05-67.2 kg/hm2.
